This invention relates to rotary pumps for moving water, oil and variousother liquids, and has as one-of its ob ects to pro vide a mechanicallyactuated pump 'in which valves of the usual type, and springs of any-fitted cylindrical valvesfiityprovided with Arfurther object isiin theprov1sionof an*rectili-nearports 35-ef uniform cross section"essentially compact, simple andefiicient'rog kind are whollyeliminated. 1

tary pump capablepflon'g and-continuous service. '7 ,5; 1 cw Another aimis to provide a pump that can be'chjeapl'y constructed, all partsbeing 1of simple design.

These and like'other aims and objects are atta ned by the novel design,"construction and combination of parts here1nafter fully describedand'shown in] the accompanying. an essential part of'tlns drawing, formingdisclosure, andv in which Figure 1 is a vertical sectional'yicwof arotary pump made'in' accordance with the c center sockets 37 n "WlllClIare mounted invention.

Figure 2 is a s milar'view of the same, the parts be ng in a differentposition.

Figure 3 is a vertical sectional view, taken 7 .in a plane at a rightangle to Figures 1 and 2, on line 3 3 of Fig. 1. Figure 4; is a top planview of the same. Referring to the drawing in'greater detail, the pumpcasing comprises upper'and lower portions 13 and 12 having outer wallsand 11, and inner walls 14 and 15 separated by a spacing plate 16. o,

The upper portion 13 has bolted to it a combined inlet and outletmanifold 17 in which are engaged supply *and discharge pipes 18 and 19leading to chambers 20 and 21.

The chamber 20 has inlet openings 23 admitting the liquid to passages 24and 25. be low which are cylindrical piston chambers 26 and 27. Thepassages 24 and 25 are sub stantially rectilinear, and extend frompiston. chambers 26 and 27 to the inlet and outlet openings of thecasing, their directions being substantially radial with respect tochambers 26 and 27.

A shaft 28 is journalled axially of-the piston chambers in the sides ofthe body,

mg adapted to make wiping contact with the walls ofthe piston chambers'26and as they arenloved ftherearound by the ec- 'centrics 29and30.-'-"i- In the upper part of the casing are'other cylindrical bores33] in which are rotatably.

manifold. As will bef's'e'enfrorn the drawing, each port 35 is adapted't'o assume a position in substantialalin'ement with the passage 36during the greater part of the pumping troke,tojthereby permit thepassage of liquid tl'irough the outlet passage without substantialchangc' of direction. The purpose of this arrangement 1s to minimizeeddving and consequent frictional losses in the flow of the liquid 7Both of thevalve's' 34'contain bored 01f round bars 38 to freely pivottherein. Ex-

plates 39. theirlowerjportions fitting transverse radial slots in thepistons 31and 32 respectively, these platesforming partitions betweenthe inlet and outlet passages.

In operation, power beingtransmittedto the shaft 28, the eccentricsarerotatedcans,

ing the pistons to describe circuitous paths in contact withthe'walls-of the'chambers 26 and 27 By reference to Figure 2 it'will beseen that water or like liquid entering through the pipe 18 will bedivided to pass in two streams through the inlet openings 23 to thcpassages 24: and obviously flow freely into the space between the wallsof the pistons and piston chambers, this space constantly varying involume.

The piston 31, moving in counter-clockwise direction forces the wateraround itself, and eventually through the port 35, and passage 36 intothe chamber 21 and out of the pipe 19.

The other piston obviously operates in the same manner but in oppositephase, thereby producing a substantially regular and continuous flowthrough the pipe 19.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is

1. A rotary pump comprisingapair of similar body members havin 0 enupper chambers on one side of each 0 y and ontatable on said eccentrics,cylindrical valves 7 in, the mentioned .valveseats, said valves eachhaving tangential ports vcommunicating with its corresponding chamber insaid cover,- s aid valves having bores ad acent their,peripheryparall-elwith;their axes and grooves leading thereto, pivots operative invthebores of said valves, and plates on said pivots engagingradialslots nsaid cylinders, saidplates transmitting rotary motionto said valves andserving as closures between the sidesofthebody members and for the portsin said valves.

3. A rotary pump for liquids, comprising a casing having a cylindricalpiston chambers and substantially rectilinear iulct and outlet passagescommunicating therewith, an eccentric ring piston in said chamber, acylindrical member rotatably mounted in said outlet passage, and apartition plate pivoted to said cylindrical member and fixed to saidpiston, said cylindrical member beto assumeia position in substantialalinement with said outlet passage during the greaterpart of the pumpingstroke, to permit the-passage offliquid from said chamber through saidoutlet passage without substantial change of direction.

,4. {A rotary pump for liquids, comprising a casing having adjacentinlet and outlet openings, a cylindrical piston chamber, andsubstantially rectilinear inlet and outlet passages extending radiallyfrom said piston ring provided with a rectilinear port'adapted chambertosaid openings, an eccentric ring piston in said chamber,acylindricalmember rotatably mounted in said outlet passage, and apartition plate pivoted ,to saidcyliir drical member and-fixed to saidpiston, said cylindrical member being provided with a substantiallyrectilinear port of uniform cross-section adapted to a'ssume'a position,in

substantialalinement with said outlet passage during-the greater part ofthe pumping st roke,,to permit the passage of liquid through said outletpassage without substantial change of direction.

In witness whereof I have affixed my signature.
